Question

solve 2a-3=5 by transposing the
terms and check your result.​

Answer 1

Step-by-step explanation:

2a=5+3

2a=8

a=8÷2

a=4

way of checking

2(4)-3=5

8-3=5

5=5

answer=4

Answer 2

Answer:

Given:-

Solve : 2a - 3 = 5.

To Find:-

The value of "a".

Note:-

●》For finding variables value, constant value needs to rearranged ( transposing ) that signs are also changed or not. For example - positive becomes negative ( signs are change ) , multiple becomes divisional ( signs are not change ).

●》Equations means the calculations of left hand side value is always = the calculations of right hand side value.

Solution:-

☆ Equation~

▪︎$2a - 3 = 5$

☆ According to note first point ( rearrangement or transposing )~

▪︎$2a = 5 + 3$

▪︎$2a = 8$

▪︎$a = \frac{8}{2}$

☆ After doing division~

▪︎$a = 4$

$\huge\pink{a = 4}$

Checking:-

♤ According to note second point ( equation means )~

• $2a - 3 = 5 \ \ ?$

• $2 × 4 - 3 = 5 \ \ ?$

• $8 - 3 = 5 \ \ ?$

• $5 = 5 \ \ ?$

♤ Yes!

$\huge\pink{ Hence, Proved \ \ that : a = 4}$

Answer:-

Hence, the value of a = 4.
